I just got a Remora clip-less holster with sweat shield for my SR9c a few days ago. I've been wearing it for at least 14 hours a day (one day included 3-4 hours of yardwork). It's been much more comfortable that I expected. Because there's no clip, you can adjust the cant to anything you like. It doesn't require a heavy gun belt, I'm wearing a well-worn and well-broken-in belt that I've been wearing for a few years. The holster DOES NOT MOVE. The gun is secure and the holster is comfortable. I may have FINALLY found the right holster !!!
... now what do I do with the drawer full of experiments ?

I gotta go with Crane on this one as I do not have a SR9C, but every one of my carry weapons have a holster very similar to the Tommy Theis holster. Mine are home made and very comfortable, secure the weapon without question, and are easily concealed.
